I think I'm also affected by this bug. I'm running on a desktop system with an ATI Radeon HD 5670. The symptoms I'm experiencing aren't a complete hang -- the mouse cursor still works as do the Ctrl-Alt-F* combinations to flip to the console, but the whole screen is black (except for a small rectangle in the lower-right corner, but even that is unresponsive).
I've upgraded fglrx to the PPA version (2:8.850-0ubuntu1~xup2~natty) but it doesn't seem to help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778380 Title: compiz freeze with cpu 100 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/778380/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
